| Abstract: | Under field condition,the effects of potassium application rate on photosynthetic characteristics and yield of summer-planted peanut were studied by using the technology of film mulching cultivation.The net photosynthesis rate,intercellular CO2 concentration and stomatal conductance were measured with Li-6400 Portable Photosynthesis System with an open flow gas exchange system.Among all treatments,the potassium application rate as 150 kg/hm2 recorded the highest value of leaf area index,chlorophyll content,... |
